PASSIVE INTERMODULATION DISTORTION MEASURING METHOD AND SYSTEM - According to a reception passive intermodulation measurement method of the present invention, a device under test is set to the mismatching condition, and a standing wave is generated on a transmission line where the sample is connected. Since the tip of the transmission line is short-circuited using the sample, the sample is positioned at the anti-node of the standing wave, and test signals are applied at a high current density. System noise is calibrated with the tip of the transmission line being open. Since impedance matching is not required and terminators are not employed, a large measurement dynamic range is obtained without being affected by passive intermodulation that is generated in terminators. The sample is very small, and an arbitrary shape can be selected. The property measurement is enabled for a wide range of materials, regardless of a conductive material, an insulating material and a magnetic material.

In the third step, preliminary pushing of the upper surface of the secondary product is performed to obtain a tertiary product where a recess generally matching the longitudinal section in the axial direction of the bottom wall of a cup portion of the final product is formed in the upper surface. In the fourth step, a quaternary product having a cup portion provided with a ball rolling groove in the inner wall is formed by performing backward extrusion of the tertiary product by using a punch having a tip shape generally matching the longitudinal section of the recess. Finally, in the fifth step, an outer ring member is produced as a final product by performing ironing of the cup portion of the quaternary product.

OPTICAL MODULATOR - An optical modulator having a high stability is provided. In the optical modulator according to the present invention, a phase modulation by an electro-optic effect is made on an optical substrate of an electro-optic material while the setting of an operating point by a thermal-optic effect is made on a planar lightwave circuit (PLC) substrate of quartz, silicon, or the like. Such configuration can suppress the influence of thermal drift or the like because no heat is applied directly to the optical substrate of the electro-optic material. In addition, breakage and warpage of the substrate due to heat are also mitigated. Further, quartz used for the PLC has a low thermal conductivity, approximately one-fifth of that of the LN substrate (approximately 1 W/(m·K)), and therefore, a desired phase difference can be maintained with a low power consumption, and thus, the operating point becomes stabilized.

RARE EARTH MAGNET HOLDING JIG AND CUTTING MACHINE - A magnet holding jig comprises a platform and first and second holders disposed on opposite sides of the platform. The platform is provided with channels, the holders are comb-shaped to define digits and slits, the channels and the slits being aligned to define guide paths for permitting entry of a cutting tool therein, and the holders are also configured as digitate hooks. The holder hooks are in contact with a rare earth magnet block resting on the platform. The holders are pushed inward at their lower portions so as to elastically deform the digitate hook and move it backward and to bring the hook digits in pressure abutment with the magnet block, thereby holding the magnet block in place on the platform.

Water treatment apparatus - It is an object of the invention to provide an effective technique for detecting the quality of water with high accuracy. A representative water treatment apparatus includes an aerobic treatment region that treats water aerobically, a downstream region in which the water aerobically treated in the aerobic treatment region flows, a water quality sensor that is submerged in the downstream region and detects the water quality and a sensor washing arrangement that washes the water quality sensor by supplying the water of the downstream region to the water quality sensor at a flow rate higher than water flowing around the water quality sensor. As a result, sludge generated due to aerobic treatment can be prevented from being deposited on the water quality sensor and/or deposited sludge can be removed, so that the accuracy of water quality detection of the water quality sensor can be enhanced.
